These days, living inside a bubble is beginning to look more and more attractive. South Korea is planning to construct a series of giant eco domes that mimic the world's ecosystems while providing a place for scientists and regular citizens to study the environment.

Designed by SAMOO Architects and Engineers, the Ecorium Project
spans 33,000 square meters and will feature an education center, a wild
plant area, a wetland reserve, an environmentally-focused think tank,
and a large system of interconnected greenhouses.

To fight malaria, a mosquito-borne illness, Nathan Myhrvold of Intellectual Ventures Lab
has designed an insect-killing laser gun. The device, made from spare
parts found on Ebay, has the ability to track mosquitoes in flight and
shoot them down with a precise death-ray.
